Hi, maybe you got also an VM creation error on OpenVZ/HyperVM..

"VM creation has failed. Reason: tar var/log/messages Wrote only 2048 of 10240 bytes tar var/log/wtmp Cannot write Disk quota exceeded tar var/log/btmp Cannot write Disk quota exceeded...."
here is more tech details about the cause

Try to create VM using other image. and then rebuild the VM using the image which failed. In my case it worked.
Im unsure what is the cause

Also if not worked, you may try first set higher ram, disk to the VM and after build, change back to low values.
